Introduction

Industrial Visit Coursework Amy Blackwell 12MW White Horse Leisure Centre, Wantage. Introduction I visited the White Horse Leisure Centre in Wantage, this is the local town sports centre. Its facilities include a swimming pool, gym, dance studio, tennis courts and large sports hall where many activities take place such as basketball, badminton and trampolining. Physics is used through out the sports centre in the equipment and the building itself, I am looking at two of these situations where physics can be applied to sport. Heating the Swimming Pool The swimming pool is 25m long by 12.5m wide and kept at a temperature of 29.5�C; this is maintained by a constant circulation of water. The water level is kept just above the pool rim this means water flows over the edges and into drains around the whole pool. This water is then heated under the pool and pumped back in through many small jets along a central panel positioned along the length of the pool. This constant heating of the pool is necessary to maintain a comfortable temperature for users and prevent risks of hypothermia; this costs the centre money but is necessary for comfort and safety. The temperature falls due to heat loss, this happens all around the pool but mainly on the surface due to the cold air surrounding the pool. This heat loss will be mainly due to evaporation, this is where water particles have more energy than normal so are able to overcome forces of attraction and escape from the surface of the liquid. ...read more.

It is also there to provide a comfortable and safe surface for the trampolinist. Storing Energy I will concentrate at looking at the physics properties of the springs and bed in relation to the storing of energy. The original energy with in the system is from the trampolistist by bending their knees and pushing off against the surface. When the trampolinist lands this stretches both the surface and the springs therefore storing elastic potential energy. This energy can be calculated by E = 1/2 kx� where k is the stiffness of the material and x is the extension. The stiffness of the material can be calculated by Hooke's law where the stiffness (k) is equal to the force applied (F) divided by the extension, which is the additional length of the material after a force has been applied. The stiffness of the springs and material is therefore a very important factor if they were too stiff not enough energy would be returned and where they not stiff enough this would result in injury as the material may reach the floor. By the laws of energy conservation this energy cannot be destroyed, most of the energy is immediately returned to the person therefore pushing them back in to the air. However the material is designed so it is not 100% efficient or the person would continue bouncing indefinitely. ...read more.

Conclusion

and less from the bed, which needs to stretch more to prevent injury. This arrangement gives the maximum dip at the centre of the trampoline where you land. Strengths, limitations and other uses of this principal. As I have said one limitation of this is that not all the energy is returned to the gymnast also although the physics of the equipment is important skill and fitness is required to be a successful trampolinist. Safety also limits what is possible in terms of making the best use of the energy. However without the use of these physics principles and the selection of correct materials many of the moves performed would not be possible also with out this understanding many more injuries would have occurred. Trampolines are being further developed to increase the standard with in the sport and increase safety also trampolines are being developed for use in gardens. The social impacts of trampolining are that people meet at a club and enjoy participating in a sport. Economically trampolines also make money for the leisure centre, as they are able to hire them out to paying groups. The principles of energy conservation used here are the same as those used in sports balls such as tennis balls, running shoes, children's bouncy castles and bungee jump cords! It is also used in small exercise trampolines, here the efficiency is much less and material stiffer so more effort is required. Also stiffness is an important property of many materials such as floors, wires, metals e.g. in car panels and elastic bands. ...read more.

Some rowers need to take special care with pre-race eating - it can be very uncomfortable to race with a full stomach. With much of the day tied up in preparation and the race itself, there is usually little opportunity for rowers to meet their usual high-energy intake.

If we decide through some democratic process what level of protection we want to give to 'life and nature', then we can charge fees on disturbance of life and nature, whether paving, monoculture, pollution, taking of living things for food or other use, or whatever, and the prices we see

Between 50�C and 60�C, there was a drop in the rate of respiration of 0.5000cm3/min. This is because the enzyme and the substrates had too much energy at this temperature, and vibrated too much. This caused the enzyme's active site to start to denature, and the substrates couldn't bind as much with the active site.

The machine then emits ultrasound waves through special pads into the gel and then to the body. The wave is absorbed by some tissue but passes through others and is reflected by still more. The reflected waves travel back up through the body into a sensor which is linked to the ultrasound machine.

into its active form, Trypsin, so therefore the other enzymes become activated. Task 6: My technique for diagnosing these samples was limited and the main reason for this is because my results that I obtained were only qualitative and not quantitative.

With the increasing in human population, demand for more energy is needed. But can we only rely on nonrenewable resources? Nonrenewable resources are being depleted so fast everyday. It is true we have alternative renewable resources, but as these resources are expensive to use, we therefore as humans prefer the nonrenewable ones.

mass tends to infinity this means that there would need to be an infinite amount of energy needed to push us past this speed barrier; This equation represents what would happen to mass when relativistic speeds are reached. Here, m is the mass, of an object at rest; m' is the value for the moving reference frame.
